{"product_id":"tk-02-07-0141","title":"Drive Chain Gold \u0026 Black 420-110L Ape50","description":"By making the link plate thicker than standard products, the strength is increased by approximately 1.2-1.3 times (compared to SP Takegawa).\u003cbr\u003e\nFurthermore, it is the strongest 420 series drive chain equipped with SDH treatment and solid bushings.\u003cbr\u003e\nSDH Treatment\u003cbr\u003e\nThe cause of chain elongation is wear between the pins and bushings.\u003cbr\u003e\nWhen fine, hard, harmful particles such as sand and dust enter between the pins and bushings, they accelerate chain wear, causing vibration and noise, and shortening the chain's lifespan.\u003cbr\u003e\nIn such cases, D.I.D's proprietary SDH treatment proves its effectiveness.\u003cbr\u003e\nSDH treatment forms a very hard film on the pin's surface, and this film contains highly hard carbides dispersed within it.\u003c\u003cbr\u003e\nTherefore, it prevents chain wear even if hard foreign particles enter between the pins and bushings from the outside.\u003cbr\u003e\nSolid Bushing\u003cbr\u003e\nThis is a roller chain with excellent wear resistance that uses highly rigid solid bushings with a seamless, smooth surface and excellent roundness.\u003cbr\u003e\nSolid bushings reduce the barrel-shaped deformation of the bushing that occurs when it is pressed into the link plate, forming an optimal contact bearing surface between the pin and bushing.\u003cbr\u003e\nChain size: 420\u003cbr\u003e\nColor: Gold \u0026 Black\u003cbr\u003e\nNumber of links: 110 links\u003cbr\u003e\n*The image is for illustration purposes only, and the design and specifications of the products shown are subject to change without notice.
